Inconel 725 alloy is a nickel-chromium-molybdenum-niobium alloy. It has excellent corrosion resistance. After aging heat treatment, it can greatly increase the strength of the alloy and greatly improve the ductility and tensile properties of the alloy. The alloy also has strong resistance to stress corrosion. Used for pipe fittings, joints and bearings in acid-resistant equipment. It is also widely used in marine marine equipment
